Claims.

My present invention relates to an improved door check and closer of thetype generally comprising a pair of spring pressed pivoted arms, one ofwhich is adapted for mounting on the door and the other on the doorframe, and including friction means traveling along the arms to efiect alimitation to the opening of the door and then to effect a gentleclosing of the door.

In the accompanying drawings I have illustrated one complete example ofthe physical embodiment of my invention according to the best mode Ihave thus far devised but it will be understood that various changes andalteration may be made in the exemplified structure within the scope ofthe appended claims.

In the drawings:

Figure 1 is an end elevational view of the check and closer of myinvention shown as mounted on a door and its frame.

Figure 2 is a top plan view thereof.

Figure 3 is a partial horizontal sectional view showing the latch meansfor the travelers.

Figure 4 is a vertical sectional view showing the structure of Figure 3.

Figure 5 is a partial horizontal sectional view showing the springcloser means for the pivoted arms.

Figure 6 is a horizontal sectional view showing the structure of Figure5.

Fig. 7 is a plan view of the whole device on an enlarged scale, portionsbeing broken away to show details of inner construction.

Referring now to the drawings wherein like characters are indicative oflike parts, I have illustrated the present embodiment of my invention ascomprising a pair of channeled arms 2 and 4 having end bearing disks 6and secured in pivotal relation by the bolt 8. A spacer disk is locatedbetween the bearing disks or ears of the arms as at 9, and the bolts Illsecure the ends l2 of the coil spring l4 located about the spacer disk.

Near the free ends of the arms 2 and 4 I have slotted the channels as at[6 to form the strips I8 which are expressed from the base of thechannel curving from end to end for the pur pose to be hereinafterdescribed.

On the free end of the arm 4 I employ a pair of spaced ears 20 having abracket 22 to which is secured an attaching flange 23, and the bracketis pivotally secured to the ears by pin 24. This bracket is attachedsuitably to the door D.

On the free end of the arm 2 I have provided a collar 26 disposed withinthe U-frame 28 that is rigid with the arm 2. A pivot pin or stud 30extends through the collar and is rotatable therein. The stud projectsabove and below the arm 2 and at one end is secured against accidentalwithdrawal by a cotter pin 34, while the opposite end of the stud hassuitably secured thereto, as by welding, an attaching flange 32 adaptedfor mounting on the frame F of the door D. By removing the pin 34 andreversing the position of the flange 32 and the stud with relation tothe arm 2, the door check and closer may be adapted for doors openingeither to the left or right.

In order to limit theoutward movement of the door and to retard theclosing of the door against the tension of the spring I4, I employ oneach arm a traveler 36 having flanges 38 shaped to encompass thechanneled arms and the flanges are formed with ears 40 carrying axles 42and rollers 44 which bear in the opening movement upon the outer surfaceof the arms.

In addition, the journal disks 46 extending inwardly from the flangesbeyond the arms carry axles 48 journaling the rollers 50 which ride inthe channel of the arms and bear against the inner surface during theclosing movement of the arms. During the closing movement these latterrollers abut each other as well as the arms and the frictional contactbetween the rollers 50, and between the rollers 50 and the arms retardsthe closing of the door.

The travelers 36 are connected by means of the arms 52 pivotally securedto the rear axles of the rollers 44 and urged against the extendingaxles 48 by springs 54 thereby pressing the travelers away from eachother during the closing of the door, thus to force the rollers 50against the inner surfaces of arms 2 and 4. The arms 52 are pivotallyconnected by pin 56.

From the above description of the structure of my invention it will beapparent that as the door is opened the arms 2 and 4 will swing on theirpivot 8 against the tension of the spring I 4 and the travelers willleave the depressed strip in which the rollers 50 are detachablyretained. The arms 52 will pivot on 56 and will assume an alignedposition pressing all the rollers 44 against the outer surface of thechannel arms. According to the structure illustrated, the arms 52 mayswing about their pivot until they are aligned, but any suitable meansmay be employed to further limit the movement of the arms 52 if sodesired.

When the door is released from the opening pressure the spring I4 willurge the arms in reverse movement, whereupon the connecting arms 52 willbreak from their extended position and will be urged against the axles48 thus pressing the rollers 50 into the channels of the arms 2 and l.The friction thus created between the rollers abutting, and the rollersand the channels of the arms will retard and slow the movement of thearms until the rollers reach the depressed strips |8 at which point themovement stops and the door is closed.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent is:

1. A door check and closer comprising a pair of pivoted, spring-pressedarms adapted for mounting respectively upon a door andlits frame,connected travelers on the arms, rollers onth'e travelers engaging theouter surfaces ofthe'ar'm's as the door is opened, and friction rollers0n the travelers disposed between the arms and engageable with eachother and the inner surfaces of the arms as thedoor is-eloseu undertensiono f spring pressure and retarding theolosing.
